摘要
热采是目前开采稠油的常规方法,但是其采收率较低。为提高稠油采收率,近年来发展了新的稠油开采技术。主要包括:稠油热/化学驱,蒸汽辅助重力泄油技术(SAGD)及配套技术,超稠油HDCS强化采油技术,稠油化学驱等技术。文中详细阐述了这几种采油技术的国内外发展现状及其作用机理和特点。认为随着科学技术的发展和对环保要求的不断增强,这些技术必将是未来开采稠油的主要方法。
Thermal recovery is a conventional method for developing heavy oil reservoirs.Because of its low oil recovery,new techniques,including thermal/chemical flooding technique,SAGD technique,HDCS enhanced oil recovery technique and chemical flooding technique were developed to improve heavy oil recovery in recent years.The paper introduced the development status,the mechanisms and the characteristics of these techniques.And the investigation indicates that with the development of science and technology and increasing requirement on environmental protection,these techniques will be the main techniques for heavy oil development.
